The present invention relates to certain alcohol alkoxylates of the amphiphilic type, to agrochemical agents comprising them, and to the use of the alcohol alkoxylates as activity-improving adjuvants in the agrochemical field and particularly in the field of plant protection. The alcohol alkoxylates are alkoxylated alcohols of the formula (I) R—O—[(Cm1H2m1O)x—(Cm2H2m2O)y—(Cm3H2m3O)z]co—[(C2H4O)p—(C3H6O)q]co—Z  (I) or the formula (II) R—O—(Cn1H2n1O)o—[(C2H4O)p—(C3H6O)q]co—[(Cm1H2m1O)x—(Cm2H2m2O)y—(Cm3H2m3O)z]co—Z  (II) where R is an aliphatic linear or branched radical having 1 to 30 carbon atoms; n1 is 2 or 3; o is 0, 1, 2 or 3; m1, m2, m3 independently of one another are integers from 4 to 16; x is a value of from 0 to 100; y is a value of from 0 to 100; z is a value of from 0 to 100; the sum of x, y and z is greater than zero; the sum of (m1·x), (m2·y), (m3·z) and the number of the carbon atoms in R in formula (I) and the total of (m1·x), (m2·y), (m3·z) and the number of the carbon atoms in Z in formula (II) is 15 to 60; p is a value of from 0 to 100; q is a value of from 0 to 100; the sum of p and q is greater than zero; Z is hydrogen or an aliphatic linear or branched radical with 1 to 13 carbon atoms, wherein the radical R—O—[(Cm1H2m1O)x—(Cm2H2m2O)y—(Cm3H2m3O)z]co— in formula (I) or the radical —[(Cm1H2m1O)x—(Cm2H2m2O)y—(Cm3H2m3O)z]co—Z in formula (II)comprises 2 to 12 branches in total and 0.1 to 0.3 branches per carbon atom.
